Other then the spectator's "Yeah he shot stuff!!!!" factor I'm not impressed.
Not really sure what lesson his daughter can be expected to take from this. Piss off Dad and he'll shoot/destroy your stuff?
While I'd be pissed if I had read that note about me, I have to say that 16 YO's badmouthing their parents and thinking life is unfair is hardly a new thing, nor is it confined to Facebook. If he's expecting this to teach his daughter never to say mean things about him behind his back, I've got some disappointing news for him, and I don't even have to be a parent to know it.
I'm not seeing anything approaching actual parenting* in the video. The 16 YO girl had a temper tantrum, then a grown man had a temper tantrum, and thanks to the internet we can see them both not learn anything. Yippee, I guess.
* I should mention that I can only imagine how stressful a teenager, much less a teenage girl is to live with. I don't expect parents to be calm and collected at all times, but if you're going to lose it for a little bit (which is understandable) don't post it on the net and pretend it's good parenting.
